The record time for a tour de france cyclist to ascend the 1100-m-high alpe d'huez is 37.5 min . the rider and his bike had a mass of 65 kg. at the average speed of the ride, the metabolic power to ride on level ground would be 700 w. to this, we must add the power to make the climb. what was his total metabolic power?

Increase in the gravitational potential energy of the cyclist to rise the top of the mountain is given as

given that

m = 65 kg

g = 9.8 m/s^2

h = 1100 m

now from above equation we will have

now it will take total time t = 37.5 min

so power consumed in this process is given as

now total metabolic power required for this is given as

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
